GUI to edit/update CSV

Hey guys,

I´d need some help as I can´t really get this working.

I have a CSV File like IP,NAME,PATH and I need to create a small GUI that makes this CSV editable for users. With editable I mean a single row, a single "cell" or creation of a new row.

I may not be the most efficient way but I´d have no problem with re-writing the whole CSV file new each time something changes, but I can´t get the GUI part to be working...

Maybe somebody did something similar and would share me some lines?

Any help appreciated. Thanks in advance LBH
